By Swami Harshananda
Āhvāna literally means ‘invitation’.
During the Vedic sacrifices, gods have to be invited to come to the yāgaśālā or the sacrificial shed to receive their share of the offerings. During the śrāddha or obsequious rites, the pitṛs or manes have to be invited to come and receive their offerings. Both these are done with appropriate mantras. This act of inviting is technically called as ‘āhvāna.’
In pujā or ritualistic worship, āhvāna is considered as one of the upacāras or items of service to honor the deity. The particular mudrā or handpose exhibited during the act is called ‘āhvānī- mudrā.’
